Are the women in Northeast China really the descendants of Jurchen during the confrontation between Song and Jin Dynasties in the late Ming Dynasty?

Actually, it's not. In the Song Dynasty, women did live in the Northeast for a long time. In the Jin Dynasty, a large number of people moved into Han areas, such as Hebei, Beijing, Shandong and Inner Mongolia. Before the end of the Jin Dynasty, they were severely sinicized, just like the Han people. Nuzhen, who stayed in the northeast, still lived a primitive life, and later integrated into other ethnic groups and later Manchuria.

Jurchen in the Ming Dynasty was actually a Tungusic language family from Siberia to the northeast of China, which was led by Mongolian ancestor Monge Timur. Because of the geographical relationship, the Ming people also called it Jurchen.

Therefore, you can see that the characters of these two Jurchen ethnic groups are different, and both of them quickly entered the stage of civilization from primitive society through sinicization. Of course, people can't tell the difference between them. It is said that when the Eight Banners of Manchuria entered the customs, a large family of Hong Yanzu took the initiative to take refuge in Manchuria and merged into the Three Banners.
